If the intake door mode on FATC is different from the actual intake door mode, check
as below. ▶
Turn the ignition switch to ON position.
Measure the voltage between terminal P1 and P2 (approx. 12 V) and terminal a and b
(approx. 5V).
If the voltage value is out of the specified value, check the related circuits for open.
If the circuits are in normal condition, replace the air door actuator assembly.
If the voltage is within the specified value, replace the mode door actuator assembly.
Connect the positive (+) and negative (-) cables of temporary power supply to the air doo

6) Thermo AMP
The thermo AMP outputs the compressor ON or OFF signal to ECU to prevent evaporator from
freezing. The sensing part of the thermistor is the evaporator fin contact type.
Remove the thermo AMP and measure the voltage between terminal No. 1 and 2 on the
connector.
Check whether the output voltages (ON: approx. 12 V, off: 0 V).
If the voltage value is out of the specified value, replace the thermo AMP. If the circuit is in
normal condition, check as below.
Turn the ignition switch to ON position and turn on the air conditioner by pressing the
A/C
button. And measure the voltage between terminal A12 and A11 on the FATC controlle
r
connector. (standard: approx. 12 V)
If the voltage value cannot be measured, check the circuit for open. If the measured value is
within the specified range, replace the FATC controller.

9) Micro Controller
This device receives the impact signal from the sensor for vehicle impact and identifies whether
the current condition is necessary for airbag deployment or not. And then the controller sends
the specified currents to the airbag ignition circuit as needed.
This device always monitors the airbag system in conduction with the diagnostic circuit. When it
is detected any problem, it illuminates the airbag warning indicator to inform driver of the fault
and stores the fault information.
10) Airbag Warning Lamp
The instrument cluster contains an airbag warning indicator bulb to verify the operation of the
AIRBAG indicator and sensing and diagnostic module (SDM).
The SDM performs a turn-on test when the ignition is turned ON. The SDM flashes the
AIRBAG
indicator seven tomes by supplying an intermittent ground to the indicator lamp circuit.
After
flashing seven times, the AIRBAG indicator will turn off if no more malfunctions have been
detected.
